The problem
Mercedes-Benz USA, LLC (MBUSA) is recalling certain model year 2016 GLC 300 vehicles manufactured June 16, 2015, to November 3, 2015, and 2016 GLC 300 4Matic vehicles manufactured July 16, 2015, to November 3, 2015. The steering columns in the affected vehicles may have the wiring harness for the switch module incorrectly routed. As a result, the harness may chafe and the air bag may unexpectedly deploy or the engine may stall.
The risk
An unexpected air bag deployment or engine stall increases the risk of a crash.
The fix
MBUSA will notify owners, and dealers will inspect the wiring harnesses, properly rerouting them as necessary. Any damaged harnesses will be replaced. These repairs will be performed free of charge. The recall began on April 22, 2016. Owners may contact MBUSA customer service at 1-800-367-6372.
